Hi, for the high pitched notes check your octave range settings on MCC, there's also a video with that bald head guy form arturia showing features and explaining how to set up your cv's. Video quality is the same than arturia's products quality
For your drum software check your midi channels setup (both DAW and MCC), looks like your 3 sequencers are using the same channel to control your addictive drums. Try this basic setup in MCC: Seq 1 >CH1; Seq 2 >Ch2, Drum Seq >CH10
And check the manual, must talk about all that.
cheers
